strum-METAL CONTAINEEt.

To all whom it may concern:

Be it known that I, J 01131 ToTTnRnALE, a

citizen of the United; States, residing at tainer are interlocked with the body th'ereof, all substantially as shown and described and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective view of the container, par:

- tially sectioned in the lower portion and partially completed in the lower. portion as will hereinafter more fully appear. Fig. 2 is a vertical sectional elevation of the container with the lower head fully engaged and the upper head in position to be engaged. V

Fig. 3 is a sectional view of one of the heads or ends of the container, and Fig. 4e

is an enlarged sectional detail as hereinafter fully described. Fig. 5 is a blank sheet from which the body of the container is formed.

At least two, important original features are believed to be present in the foregoing construction, viz :the five-fold hand engageable chines and the slitted or slotted inturned flanges or engaging edges of the ends of the body over the flanges of the heads or ends of the container or vessel, as will now appear.

Thus, the body I) of the vessel, container, cask or package, as one may prefer to term the article, is fashioned from a piece or plate of suitable sheet metal, and which in some instances, at least, is galvanized and has the original shape seen in Fig. 5 after being died or stamped up for the purpose. The said blank is then bent into a tube and the edges 2 thereof interlocked in a seam or fold 3. The end portions oredges of the blank are provided each with several slits or slots 4, of which there may be three or more as shall best promote the subsequent construction and use, and said slots come into the inturned flange 5 of the chine proper and which overlaps the opposite flange 6 of the head or end it of the vessel.

however, is the formation ofl'the annular beads 7 in body Z) near its' ends and which form inside shoulders serving as abutments for the heads and against which the heads are firmly locked by the inturned flanges 5.

The said slits, obviously, areimportant'in this arrangement of parts as they allow the said flange 5 to be bent in sections or portions at a time, as seen at the top in Fig. 1, where one section is down and the others are up or unturned. Obviously, also, by this construction of said flange the said sections can be opened or turned back by means of a suitableinstrument and the head removed, and both'heads or-ends are alike in these particulars.

Now, in order to obtain the flanges 5 as andgfor the purpose set forth, the ends of the body are formed with a three fold thick-;

ness, the stock being folded back upon itself with one fold upon the other and the outer fold having the flange 5 as its own outer extension, as seen in Fig. 1. The said folds or laps 8 and 9 are equal in depth to the depth of the chine,"and which in a'vessel or casktcontaining nails or in fact any other heavy contents, is a necessary feature of construction so that the vessel can be like wooden vessels or kegs heretofore. The

said. folds Sand 9 are upon the outside of the vessel and are equal in depth, and the flange 6 on head it makes practically a fourth lap or ply and the inturned overlapping edge or flange 5 constitutes a fifth lap or ply, but these latter are on the inside of the chine while the two others, 8 and 9, are on the outside thereof. This brings the stock of the body indicated by 10 below or outside ofbead 7 between the two outer folds and the two inner folds orlaps, and thus a chine is produced which is five deep in lapped and solid formation and which gives the end and head of the vessel exceptional firmness and provides a practically rigid grip of the requisite depth for the hands.

1 Yet, bymeans of-the slots 'or slits 4 the flange 5 can be opened and the head removed.

Only three splits or slits are shown in the present construction of the extension 5, but as many more may be used as the grade or weight of the metal may seem to require and which will best promote the bending of the sections of the extension lying between said slits.

The outer laps 8 and 9 are of the essence of the present invention because by means thereof I obtain a reinforced chine not possible otherwise and which makes it possible to employ a lighter sheet metal in the manufacture of the cask than would be practicable if such reinforcement were omitted, yet by reason of the construction shown the outer fold 9 is flush or even with the outer surface of the body of the vessel.

What I claim is: i

A packing vessel made of sheet metal and having chines five layers of the metal in depth, two of said layers being on the outside and two inside and comprising a flange JOHN TOTTERDALE.
